(54)	Superconductor quench monitoring and control system and method of operating the same

(57) A rotating machine comprising a superconductive coil (12) and a temperature sensor (38) operable to provide a signal representative of superconductive coil temperature. The rotating machine may comprise a control system (20) communicatively coupled (18) to the temperature sensor. The control system may be operable to reduce electric current in the superconductive coil when a signal representative of a defined superconducting coil temperature is received from the temperature sensor.
